Windows only: Freeware application doubleTwist converts your DRM-laden iTunes purchases to DRM-free MP3s that you can play pretty much anywhere. In addition to the DRM-stripping (which really is the marquee feature), doubleTwist is actually a full-fledged tool for sharing music with friends and syncing your iTunes library to any device—currently supporting devices like the PSP and Sony phones, Nokia N-Series phones, Windows Mobile phones, and even the Amazon Kindle. The DRM-stripping isn't lossless (sound degradation is reportedly about 5%), but at a conversion rate of about 100 songs per half hour, it's very fast. Brought to you by DVD Jon (the guy famous for cracking DVD encryption), this freeware, Windows-only (for now) app can free you from the shackles of Apple DRM.
